Does sale receipt double my income? should i create an invoice and then go in and receive payment

Creating a sales receipt will not double your income, @Fernando2547.

In order not to double your income, when recording one, you can choose to either create an invoice or add a sales receipt. An invoice is used when your customer agrees to pay you later while a sales receipt is used when your customer pays you on the spot for goods or services.
